Replying to Making boots fit on a Budget

Hey Gear Talk, (and tomPietrowski?) I need you thoughts on what I should do about my boots. They are Fischer Viron V8XTRs fro two seasons past that were previously rentals which I picked up for dirt cheap last season. I didn't want to invest in an expensive, fitted pair of boots until I was sure that they would fit me for a few solid years. I think that next year will be the one to get a real pair of boots and proper work done, but for now I need to make do with these guys. The problem is that they have serious fitment issues. They are somewhat stiff for me at 6'2" 150lbs, which I like, and they fit nice and tight around my calf. Unfortunately, I have very narrow and shallow but long feet, so I'm in a size 32 shell with a toe box and heel cup that are way to big for my foot. This means that I get some mean heel lift and the boot can't really grip my foot even when tightened to its maximum settings. The liner is quite packed out, but not completely gone, and I'm not quite sure if this liner is compatible with Fischer's vacu-forming tech. So, in essence, I need to make these boots fit me for a season without dropping a ton of dough. What are my options? I was thinking some not-so-custom footbeds would work to better fill out the toe box and heel, but I would really like the opinions of some more experience people on here. $100 is probably my budget, but I don't know how much I can do for that little. Should I go to a bootfiter with my requirements and get their opinion, or could I just get a shop to make me a footbed? Any help would be greatly appreciated!
